Procedure

In a 10 mL microwave vial 6-(4-(2-chloroethoxy)phenyl)-N-methyl-2-(pyridin-3-yl)quinazolin-4-amine (70.0 mg, 0.179 mmol) and morpholine (0.155 ml, 1.791 mmol) were added in methanol (3 mL) to give a yellow suspension. The vial was irradiated at 150° C. in the microwave for 30 min. The volatiles were evaporated in vacuo. Water (10 mL) was added to the reaction mixture and extracted with ethyl acetate (2×10 mL). The organic layers were combined and washed with brine (1×20 mL), then dried over MgSO4, filtered and concentrated. The residue was purified by column chromatography on basic silica gel (eluted with hexane/ethyl acetate 3:2 to 0:1). The product was obtained as the parent and converted to the HCl salt by addition of 4 M HCl-dioxane, then crystallized from EtOH-H2O to give 55 mg of N-methyl-6-(4-(2-morpholinoethoxy)phenyl)-2-(pyridin-3-yl)quinazolin-4-amine as a yellow powder (60% yield), LCMS m/z=442 (M+1) (Method D) (retention time=1.12 min). 1H NMR (300 MHz, DMSO) δ 11.31 (s, 1H), 10.41 (s, 1H), 9.63 (s, 1H), 9.10-8.79 (m, 3H), 8.34 (d, J=8.2 Hz, 1H), 8.28-8.12 (m, 1H), 7.92 (d, J=8.0 Hz, 2H), 7.87-7.74 (m, 1H), 7.18 (d, J=8.0 Hz, 2H), 4.60-4.46 (m, 2H), 4.06-3.91 (m, 2H), 3.91-3.74 (m, 2H), 3.67-3.41 (m, 4H), 3.38-3.09 (m, J=10.1 Hz, 5H).
